BOLSTER.

SPECIFICA'JTION' forming part of Letters Patent N 0. 601,032, dated March 22, 189.8. i Application filed February 4, 1898. Serial No. 669,155. (No model.)

To all whom, t may concern.-

Be it known that I, CARL E. BAUEra'a citizen of the United States, residingin Chicago, county of Cook, andl State of Illinois, have invented certain new and useful Improvements in Bolsters, of which the following is a specification.

M y invention relates to bolsters formed of metal such as are used in car construction, and while it is particularly designed for service as a body-bolster it may also, if desired, be utilized as a truck-bolster.

In the construction of my improved bolster I preferably employ the common forms of what is known as commercial rolled iron, but as the essence of my invention embodies features of merit independent of the particular kind or description of iron usedin the construction it is of course to be understood that I do not limit myself to a bolster formed .Y Yofthelass vof iron specified, but-would-include all known equivalents as within the vscope of my claims.

The objects of my invention are to provide a bolster of great strength which will be light in weight; cheap to manufacture, easy to repair, and which will have asecure and unyielding form of connection at its ends.

A further object of my invention is the provision of a tension member composed of a piece of metal having a web and flanges andthe flanges cut away at the ends to form a tongue adapted to be bent around the ends of the compression member. The above, as well as such other objects as may hereinafter appear, I obtain by the construction illustrated lin the accompanying drawings, in

v which- 2 2 of Fig. l.

yare cut away at the end, for a purpose which will be hereinafter more particularly described. Fig. 5 is a side view, partly in section, of a modification of my improvement, in

which, in place of the plate which I prefer to use as a compression member, I have substituted a channel with its' flanges pointing outwardly. Fig. 6 illustrates the channel with the flanges pointing inwardly. Fig. 7 is a section on the line 7 7 of Fig. 5. Fig. 8 is a section on the line 8 8 of Fig. 6. Fig. 9 shows the tension member with its flanges turned outwardly and embraced between the flanges of a compression memberwhich is wider than the tension member, and Fig. 1O is an end ting away the flanges of the same for a short distance from the ends, as shown at 15 in Fig. 4. At each end of the bolster the plate is arranged to pass between the flanges of the tension member, as shown in Fig. 2, thus making the structure more secure against lateral displacement of the parts.

In Fig. 3 I have shown the end of the compression member 10 cut off square and a fillingblock 16 inserted, the tongue 13 of the tension member 11 being formed as before and bent around the filling-block. Fig. 5 illustrates the same form of tension member 11, but has combined therewith a channel 17, the flanges of which are directed outwardly and the end of which is secured, as in the former construction, by bending around' it a tongue which is formed upon the end of the tension member in the manner already described. In Fig. 7 I have illustrated the manner in IOO cut away, as shown at 20, to permit the joint to be formed upon the end, the tension member Il, with the tongue I8 upon it, being substantially the same as that already described. In this construction I have inserted a second iilling-piece 21, adapted to assist in holding the parts together when the rivets ll are set in place. This is clearly shown in Fig. S.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a bolster the combination with acoinpression member and middle support, of a tension member formed of a piece of metal having a web and flanges, the ilanges of the Vsame being cut away at the ends to form a tongue which is bent around said compression member in a manner substantially as shown and described.

In a bolster the combination with a middle support and a tension member hooked upon its ends, of a compression member having its end doubled back upon itself and engaging the hooked end of the tension member, substantially as described.

l. In a bolster the combination with a middle support and a compression member having its end doubled back upon itself, of a channel iron tension member constructed with a tongue at its end, said tongue being wrapped about the end of said compression member, substantially as described.

4. In a bolster the combination with a middle support and a plate compression member, of a channel tension member constructed with a tongue upon its end bent around thc end of said compression member in a manner substantially as shown and described.

5. In a bolster the combination with a middle support and a plate compression member having its end doubled back upon itself in the manner shown, oi' a channel tension member formed with a tongue upon its ends engaging the ends of said compression member, and having ilanges directed inwardly so as to embrace the ends of said compression member, substantially as described.
